Accuracy - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Accuracy

The accuracy of D/A conversion is the accuracy for the full scale of analog output value.
Any output characteristic change through changes of the offset/gain setting or the output range does not sacrifice the
accuracy, which is maintained within the range in the performance specifications.
The following graph shows the fluctuation range of accuracy when the range of -10 to +10 V is selected.
The fluctuation range varies as follows depending on the ambient temperature and output range.
